ADJUSTABLE FORM FOR PAPER-BOX MACHINES.

SPECIFICATION forming part of Letters'Patent No. 699,416,dated May 6, 1902. Application filed January 30, 1902. Serial No. 91,918. (No model.)

To aZZ whom, it may concern:

Be it known that I, CHARLES I. RHODES, a citizen of the United States,residing at Bridgeport, county of Fairfield, State of Connecticut, have invented a new and useful Adjustable Form for Paper-Box Machines, of which the following is a specification.

My invention has for its object to provide a simple andinexpensive adjustable form for paper-box machines which. shall be equally applicable to either power or hand machines and within reasonable limits will render the use of additional forms for all sizes and styles of boxes wholly unnecessary, my novel form being so inexpensive to produce as to cost little more than an ordinary plain form and being capable of adjustment in a moments time to any length or width of box that may be required.

lVith these ends in viewI have devised the novel adjustable form which I will now describe, referring to the accompanying drawings, forming part of this specification, and using reference characters to designate the several parts.

Figure 1 is a plan view of my novel form, an expanded position thereof being indicated by dotted lines; Fig. 2, a side elevation corresponding with Fig. 1, and Fig. 3 is a lonstiff paper-board or preferably of light sheet metal, as zinc, brass, or iron, which may be plated or japanned, if preferred.

The sides and the ends are each made of two sliding parts, which for convenience I will term the inner and outer parts.

10 denotes the inner parts of the sides; 11, the outer parts of the sides; 12, the inner parts of the ends, and 13 the outer parts of the ends.

The inner parts of both sides and ends are preferably provided with inwardly-turned flanges 14, and the outer parts of the sides and ends are provided with flanges 15, which extend inward over flanges 14: and then at an angle to inclose the edges of said flanges 14, so that when assembled said inner and outer side and end pieces will be held firmly in place, but will be left free to slide over each other. As an additional means of holding the sides and ends rigidly together and with sufficient friction upon each other, so

that while free to be moved at the convenience of the operator they will retain any position in which they may be placed, I provide the inner parts 10 and 12 with slits or slots 16 and provide parts 11 and 13 with tongues 17, punched out from the material thereof and left attached at one end. These tongues are passed through the slits or slots and folded down upon the inner sides of the inner parts, the upper tongues being shown as turned upward and the lower tongues as turned downward.

18 denotes corner-blocks, to which the side and end parts are rigidly secured.

It will be noted from the drawings that an inner end part and an outer side part, and vice versa, may be made from a single strip of metal, although that is wholly immaterial so far as the principle of my invention is concerned.

l9 denotes intermediate blocks, one or more of which may be rigidly secured to each inner side part and, if req end parts as well.

As a means of attaching my novel form to the shaft of a power-machine I provide a block 20, having a hole 25 to receive the shaft, opposite sides of said block being pivoted to levers 21, the other ends of which are pivoted to diagonally opposite cornerblocks 18. v

22 denotes levers, shown as slotted, pivoted uired, to the inner to opposite intermediate blocks and each connected to the corresponding lever 21 by a screw-pin 23, which passes through the slot and engages the lever 21, it being understood that when these screw-pins are loosened the sides and ends of the form may be extended or contracted, remainingin any position in which they may be placed. After the form has been placed at the required adjustment it may be locked there by tightening up the screw-pins, block 20 being of course placed centrally of the form.

As a convenient means of attaching the form to the smaller shaft of a hand-machine and without removing any portion of the form, leavingit free to be shifted from powermachine to hand-machine, and vice versa, I provide a crosspiece 24, provided with a hole 26 to receive the shaft. This crosspiece is shown as attached to the block by wing-nuts 27, which engage threaded rods 28, extending upward from block 20. One of these threaded rods passes through a closed slot 29, the other through an open slot 30. When it is desired to attach the form to a hand-machine, the cross-piece is placed in the position shown in the drawings and locked there by the wing-nuts. When it is desired to attach the form to a power-machine, the cross-piece is disengaged by means of the open slot from one of the threaded rods, swung out of the way, and then looked in place by the other wing-nut.

The operation of my novel form has been so fully described in the description of its structure that additional description can hardly be required. It is sufficient to say that in use, the form being attached to the shaft of either a power or hand machine, in changing from one size of box to another the operator simply loosens screw-pins 23, moves the side and end parts in or out, as may be required to impart to the form the desired shape and size, and having obtained the desired adjustment locks the parts comprising the sides and ends together by tightening up the screwpin, it being obvious that the change of the form from one size of box to another may be made in less time than it takes to describe the operation.

Having thus described my invention, I claim I 1. An adjustable form for boxmachines comprisinginnerandoutersideand end parts, and corner-blocks to which they are secured, said inner side and end parts being provided with longitudinal slits, and said outer side and end parts with tongues which are passed through the slits and folded down upon the inner sides of the inner parts.

2. An adjustable form for box-machines comprisinginnerand outer side and end parts, corner-blocks to which they are secured, said inner side and end parts being provided with I longitudinal slits and inwardly-extending flanges, and said outer side and end parts with tongues which are passed through the slits and folded down upon the inner sides of the inner parts,and with flanges which partly inclose the flanges on the inner parts.

3. An adjustable form for box-machines comprisinginner and outer side and end parts, an inner and an outer of said parts being formed integral, corner-blocks to which said parts are secured, the inner side and end parts being provided with longitudinal slits,

and the outer side and end parts with tongues which are passed through the slits and folded down upon the inner sides of the inner parts.

4. An adjustable form for paper-box machines comprising inner and outer side and end parts, corner blocks to which said parts are secured, intermediate blocks secured to the inner-side parts,an attaching-block, levers 21 pivoted to opposite sides of the attaching-block and to diagonally opposite cornerblocks, slotted levers pivoted to the intermediate blocks, and screw-pins passing through the slots and engaging levers 21, whereby the side and end parts may be locked at any desired adjustment.

5. An adjustable form for paper-box machines comprising inner and outer side and end parts, means for securing said parts together leaving them free to slide over each other, corner-blocks to which said side and end parts are secured, intermediate blocks secured to the inner side parts, an attachingblock, levers 21 pivoted to opposite sides of the attaching-block and to diagonally opposite corner-blocks, levers 22 pivoted to the intermediate blocks, and means for locking contiguous levers 21 and '22 together and thereby securing the side and end parts at any required adjustment.

(5. In an adjustable box-form the combination with inner and outer side and end parts and means for securing them together leaving them free to slide, of an attaching-block, levers 21 pivoted at diagonally opposite corners of the side and end parts and to opposite sides of the attaching-block, levers 22 pivoted to inner side parts and means for locking contiguous levers 21 and 22 together and thereby securing the side and end parts at any required adjustment.

'7. In an adjustable box-form the combination with inner and outer side and end parts and means for securing them together leaving them free to slide, of an attaching-block, levers 2l pivoted at diagonally opposite corners of the side and end parts and toopposite sides of the attaching-block,levers 22 pivoted to inner side parts, means for locking contiguous levers 21 and 22 together, for the purpose set forth, and a cross-piece 2 L for attachment to a hand-machine, said cross-piece having open and closed slots, and means operating in connection with said slots to lock said cross-piece in or out of operative position.

In testimony whereof I aflix my signature in presence of two-witnesses.

CHARLES I. RHODES.
